This inyention relates to cultivators. Objects of 'this invention VVare to provide a .novelform of cultivator in which )a frame provided which carries the cultivator blades, and in whichl manually controlled means yare employed to lraise and lower the frame tof adjust the depth' of cut, as required. f I

Furtlier objects of ythis invention are to providea novel adjustment for the cultivator Ablades so that theymaybzeiiidividually justed to vary their angularmsetting with reference toa vertical axis", and may be ,adjusted to vary their angular setting with reference to a horitogxtaf axis.

Further objects are to provide a novel form of lifting mechanism for simultaneously lifting both the front ,and rear ends of the blade carrying frame.

' ries the tongue receiving bracket 3.

i Aniembodiment ofthe, invention is shown in the accompanying drawings in which Figure ll is a plan view ofthe cultivator;

Figure 2 is a detailed plan view of one of the blade mountings;

. Figure 3 is a longitudinal sectional view on the line 3-3 of igure l;

Figure 4l is a side elevation of the structure shown in Figure 2.

Referring to the drawings, it will be seen that the cultivator is provided with an axle 1, whose major portion is square in cross section. The ends of the axle carry the` supporting wheels 2 and the intermediate portion or central portion of the axle 'fiala ie tongue 4 is pivotally mounted in the bracket and extends forwardly of the machine.

A main frame 5 is rigidly connected to the axle, and is provided with a plurality of parallel longitudinally extending bars, as indicated at G. Preferably, a seat 7 is supported by means of a spring arm 8, rigidly attached to the axle. f

Beneath the main frame or stationary frame of the machine a movable frame 9 is provided and carri-es the cultivator blades. This movable frame is of rectangular contour and is provided with longitudinally ex` tending bars, as indicated in Figuresfl and 2. These bars carry a pair of diagonally arranged supporting members'l() which are preferably formed of strap iron. and are provided at their ends and their intermediate points with straight portions 1l.. Those straight portions have plates bolted Vthereae? .Seile Ne 152.1,.554-

with a plurality `rf spacedholeslthrougll any oneV of which fthe-"bolt` 16 may be "passed,` The bolt 14, therefore, pivotally. liogld'shle plate to the strip member, andthe boltil adjustably holds the plate thereto. VThis plate is provided as statedwitli a horiibntally extending portion 13, as may 'beseenfro'm Figure This horizontal vportion p'iyotaHy reeeives the arm l7for thecultivator blade 18, the pivotal union being secured by means of the bolt or screw 19 at the oppositeend of the plate 13. A' plurality of 'holefvsl'20' are formed through anyone rolf .which the. bolt or screw `2l may be passed to lock the end ofthe bar'or arm 175 adjustably Atojthe plate. lnthis manner,j.tlfie vcultivator blade may be rocked about a vertical axis to the desired angular position and also due to the pivotal mounting of the vertical portion 2 of the plate may be rocked about a horizontal laxis to secure the angular setting in this direction.

Themeans for suspendingor supporting the frame 9 will be described. This frame is provided on opposite sides with upwardly extending apertured lugs 22 and 23. The rear lug 22 is joined by means of a short link 24 to one arm of a lever 25, such lever being pivoted, as indicated at 26, to the appropriate bar 6 of the stationary frame.

lThe other lug is joined by means of a link 27 to the forward end of a manually manipulated lever 28 which is pivotally mounted at a fixed point, as indicated at 29 in Figure 3. This lever 28 is also connected by means of a link 30 with one end of the lever 25. Thus, When the lever 28 is rocked, the link 27 will be moved and the link 24 will be moved in the same direction due to the ylink mechanism described above and illuslme trated particularly in Figure 3. The lever 28is provided with a locking plunger 31 adapted to enter any of the notches 32 of ak l kthat the levers 28 and their associated mechanism are duplicate on opposite sides of the machine. Consequently, both sides of the movable frame of the cultivator and, consequently, all of the cultivator blades may be simultaneously raised or lowered with the utmost facility.

The frame 9 is provided with a pair of U-shaped guides 35 which straddle the squared axle l, as shown in Figures 1 and 2. The'forward endof the movableyframe is provided with aU-shaped guide 36 which is equipped .with a'plurality of apertures 37.

. This U-shaped guide straddles the tongue 4,

.asmay be seen from Figures land 2. It desired, a pair of bolts or screws 38 may be passedY through the apertures 37 on opposite sides of the tongue to hold the guide f in alixed position.

Itf will be seen that a novel Jform of cultivatorhas been provided which is so constructed that a movable blade vcarrying frame may be raised or lowered with the utmost ease. Further, it will be seen that a novel form of mounting for the blades is secured by this invention,`lwhereby the blades may be adjusted angularly either about a vertical or about a horizontal axis.

Although the invention has been described inl considerable detail, such description is intended as illustrative yrather than limiting asVv the invention may be variously embodied and as the scope of such invention is to be determined as claimed.

I claim:

A; cultivator comprising a main frame,

Vsupporting wheels carried thereby, a movmanually controlled levers, said auxiliary l lever having one end connected to its corresponding manually controlled lever at a point onthe side of the fulcrum of such manually controlled lever opposite from that connected to the said link, and a link extending downwardly from the free end 0i' each of said auxiliary levers to said movable frame, whereby said movable frame may be independently adjusted on either side and whereby each side of themovable frame is retained in a horizontal position lengthwise of the machine in all positions of adjustment.

In testimony that I claim the foregoing I have hereunto set my hand 'at Milwaukee, in the county of Milwaukee and State of lVisconsin.

PETER HENNES.
